Brexanolone can cause excessive sedation and sudden loss of consciousness, and CNS depressants like tizanidine may worsen this. The risk is significant because brexanolone is given as a prolonged intravenous infusion with mandatory monitoring.
Ce que signifie cette interaction, en termes simples
Brexanolone and Tizanidine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
